    Hi Guys, need your help here.
    i got the following problem not only with one but with two 105.012
    When i unscrew the caseback start and stop on the upper pusher
    and reset on the lower pusher work perfectly.
    But as soon as i tighten the caseback and pressure is applied to the dust cover,
    the upper pusher starts and RESETS because the pin for the lower button
    gets stuck somehow.
    I can also simulate it by pressing down the dust cover with my fingers.
    Same malfunction occurs.
    Hope you can help me out here.

    Is your dust cover inverting inward? If so it could be pressing down on something when the caseback in screwed down

    could it be that the movement ring is not perfectly aligned. Has the edge of the ring to be flush with the movement?

    Is the Operating Lever bent or raised? Sounds similar to an issue I had, and it was a bent Operating Lever.

    The operating lever is a long solid piece that runs along the edge of the case on the side where t pushers are, right on the top. You can see it here in t image below across the top of the pic, kind of grey coloured. It should be nice and flat against the movement. If it is raised up, then the start pusher can't engage properly.

    ...but I'm still pretty new here and definitely not a watchmaker by any stretch.

    Here's a better pic of the problem I had.

    That lever shouldn't be raised up like that..
